 Difference between Analog Communication and Digital Communication

1. Analog Communication : 
In analog communication the data is transferred with the help of analog signal in between transmitter and receiver. Any type of data is transferred in analog signal. Any data is converted into electric form first and after that it is passed through communication channel. Analog communication uses a continuous signal which varies in amplitude, phase, or some other property with time in proportion to that of a variable.

2. Digital Communication:
In digital communication digital signal is used rather than analog signal for communication in between the source and destination. The digital signal consists of discrete values rather than continuous values. In digital communication physical transfer of data occurs in the form of digital bit stream i.e 0 or 1 over a point-to-point or point-to-multipoint transmission medium. In digital communication the digital transmission data can be broken into packets as discrete messages which is not allowed in analog communication.

 ### Network Layer: Design Issues and Key Concepts **Network Layer** is responsible for data transfer between devices on different networks. It determines how data is routed from the source to the destination, ensuring it follows the best path. ### 1. **Design Issues in the Network Layer:**    - **Routing**: Deciding the best path for data to travel across the network.    - **Congestion Control**: Preventing network overload, ensuring smooth data flow.    - **Packet Forwarding**: Moving data packets from one network to another.    - **Error Handling**: Detecting and correcting errors that occur during data transmission. ### 2. **Routing Algorithms**: A Detailed Explanation Routing algorithms are methods used by network devices (like routers) to determine the best path for data to travel from its source to its destination. The goal of these algorithms is to ensure that data packets reach their destination efficiently, quickly, and with minimal...
